Colin Ian King f50b6805db 8250-men-mcb: fix error checking when get_num_ports returns -ENODEV ... The current checking for failure on the number of ports fails when -ENODEV is returned from the call to get_num_ports. Fix this by making num_ports and loop counter i signed rather than unsigned ints. Also add check for num_ports being less than zero to check for -ve error returns. Addresses-Coverity: ("Unsigned compared against 0") Fixes: e2fea54e45 ("8250-men-mcb: add support for 16z025 and 16z057") Signed-off-by: Colin Ian King <colin.king@canonical.com> Reviewed-by: Michael Moese <mmoese@suse.de> Link: https://lore.kernel.org/r/20191013220016.9369-1-colin.king@canonical.com Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>		2019-10-15 21:38:41 +02:00
